In a pandemic, the availability of health indicators among at-risk populations, such as elderly, is vital due to disease's rapid transmission and need act quickly contain its evolution. Traditional clinical methods for monitoring signs typically require contact-based sensors that must be precisely attached by skilled healthcare professional, are less practical repeatable measurements, not suitable long-term monitoring. Contactless monitoring, radar-based techniques or IR-thermal imaging, on...
The pathogenesis of spontaneous pediatric vertebral artery dissections (VAD) is poorly understood but most often involves the V3 segment where C1 rotates on C2. We studied children with VAD provocative digital catheter angiography and found an association between rotational compression.Seven boys (12 months to 9 years; median 4 years) presented over 38 consecutive underwent passive bilateral neck rotation.VAD were in 2 patients unilateral 5. Provocative showed dynamic compression 6...
Clinical clearance of a child's cervical spine after trauma is often challenging because impaired mental status or an unreliable neurologic examination. Magnetic resonance imaging (MRI) the criterion standard for excluding ligamentous injury in children but constrained by long image acquisition times and frequent need anesthesia. Limited-sequence magnetic (LSMRI) used evaluating evolution traumatic brain may also be useful while potentially avoiding The purpose this study was to assess...
BACKGROUND: U-shaped sacral fractures are highly unstable, can cause significant neurological deficits, lead to progressive deformity and chronic pain if not treated appropriately. OBJECTIVE: To report a case of fracture with lumbopelvic fixation decompression roots in 23-years-old man. METHOD: Decompression the combined internal reduction using iliac screws. RESULTS: Restitution lumbosacropelvic stability recovery sphincter function. CONCLUSION: Lumbopelvic is effective restoring...
To describe our experience with C1 lateral mass screws as part of a construct for C1-2 stabilization and report an alternate method C1-C2 complex three-point fixation.All patients that had at least one screw placed in the entered this study. In selected who higher chance nonunion was used: transarticular combined screws.Twenty-one were 11 patients. three used. All demonstrable solid stable fusion on follow-up.C1 are safe provide immediate stability. The use is feasible also excellent...
The goal of this study was to review the efficacy and safety different surgical techniques used for treatment Chiari malformation type I (CM-I) in children.The authors retrospectively reviewed 437 consecutive children surgically treated CM-I. Procedures were classified into four groups: bone decompression (posterior fossa [PFD]) duraplasty (PFD with [PFDD]), PFDD arachnoid dissection (PFDD+AD), tonsil coagulation at least one cerebellar (PFDD+TC), subpial resection (PFDD+TR). Efficacy...
Hemangioblastomas of the spinal cord are rare lesions, and those located at cauda equina even rarer. Most commonly these tumors present in patients with von Hippel-Lindau (VHL) syndrome. We describe here case a 48 years old woman pure radicular hemangioblastoma, not associated VHL, presenting pain, diagnosed magnetic ressonance imaging (MRI) submitted to total resection very good outcome. To our knownledge, this is second report MRI aspect histologically proved hemangioblastoma patient...
OBJECTIVE: To evaluate the feasibility, safety and accuracy of pedicle screw placement in upper thoracic spine using free-hand technique with aid fluoroscopy; to analyze methods used verify correct positioning intra postoperatively. METHOD: All patients instability cervicothoracic or at least one placed segment T1-T6 as part a posterior construct entered study. Only C-arm intraoperative fluoroscopy was guide placement. RESULTS: We obtained excellent 98.07% screws. CT scans precisely...
OBJECTIVE The long-term effects of surgical fusion on the growing subaxial cervical spine are largely unknown. Recent cross-sectional studies have demonstrated that there is continued growth through teenage years. purpose this multicenter study was to determine rigid instrumentation and by investigating vertical growth, alignment, curvature, adjacent-segment instability over time. METHODS A total 15 centers participated in multi-institutional retrospective study. Cases involving children...
Cervical traction in pediatric patients is an uncommon but invaluable technique the management of cervical trauma and deformity. Despite its utility, little empirical evidence exists to guide implementation, with most practitioners employing custom or modified adult protocols. Expert-based best practices may improve care children undergoing traction. In this study, authors aimed build consensus establish for use order enhance utilization, safety, efficacy.
Recent developments in microbolometer array technology have favored the spread of low-cost infrared cameras and their dissemination different application domains, particular, regarding medical applications. According to World Health Organization, elevated body temperature is one most common indicators an abnormal condition. Indeed, monitoring paramount, particularly pandemic scenarios like world living since late 2019. In this context, we aim develop a screening system using thermography...
Spontaneous subarachnoid hemorrhage accounts for 5 to 10 % of all strokes, with a worldwide incidence 10.5 / 100000 person/year, varying in individual reports from 1.1 96 /100000 person/year. Angiographic and autopsy studies suggest that between 0.5% 5% the population have intracranial aneurysms. Approximately 30000 people suffer aneurysmal United States each year, 60% die or are left permanently disabled. We report our experience surgical treatment aneurysms six year period, Belo Horizonte,...
